METALLIC CHAIR, sTooL, SEAT, ANDTHE LIKE.

Application f led January 28, 1921. Serial No. 440,705.

I land, manufacturer,have invented Improvements in or Relating to MetallicA Chairs,

:lowing is a specification.

I This lnvention compr1ses 'certain lmprovef ments in or relating to metalhc chalrs, stools,

Stools, Seats, and the like, of which the fol'-I seats and the like, such as are used as office chairs or stools, music stools, garden chairs, or as seats for other purposes.

.More particularly the invention relates to metallic chairs, stools, or seats comprising a `plurality of legs of tubular telescopic con-` g positionlwbeloymrthe seat level by detachable tubular`V or other members, and also braced or connected together at the top-by the seat bottom orby the frame thereof, whichseat bottom or frame' is also detachable and may .be of a character adapted to accommodate l optional ap urtenances such as a seat back or side. han grips, these appurtenances and also the seat bottom or frame thereof being of a character such that a standard construction ofvseat bottom may be manufactured and adapted to accommodate any` appurtenances which might be desired to fulfill a A K a convenient part of its length and termi- The object of the present invention is to` I' provide an improved meansof telescopically 35 adjusting the length of the legs to provide y for an adjustment ofthe height of the seat particular requirement.

bottom, said improved adjusting means be- .ing simple in 'construction and effective in use, and avoiding any weakening of the tel- '40 escopic tubular parts of thejlegs.-

According' to the `present Invention the l I 'telescopic leg adjustment comprises an upper telescopic member adaptedto -slide within the upper tubular extremity of theleg, this sliding movement'bein limited-b a pin and slot device controlled y a thum screw or' A the like, and the upper telescopie'niembers of eachpair of legs being transversely' bracedlor connected together at thetopiby a i150 flat strip member, which flat `strip members ,are adapted to; support the. seat bottomor the frame thereof. Y In order that this invention ma'y be clearly planatory sheet of drawings, upon which Figure l is a perspective view of a metallic, chalr or seat of the kind referred to andv havingthe present invention applied.

Figure 2 is a detail front elevation ofthe telescopic leg adjustment.

Figure 3 is a sectional side 'elevation of Figure 2.

Figure 4 isa cross-sectional plan on the v line 4-4 of Figure 2.

In a convenient embodiment of the pres-l 'ent Invention the legs are each tubular,

understood.land readily carried into practice,

reference maybe had to the appended ex' 55 the front -legs a being straight and th y rear legs aly of ogee configuration, `said legs being coupled together at a suitable point in their height by longitudinal and transverse' bracing members b b?. disposed preferably at differing heights. Each pair of legsa alis transversely braced or 'connected together at` the topy by a fiat strip strip c an upper telescopic depending mem,-

ber f advantageously in the form of a solid metal rod adapted to slide within -the upper extremity of the tubular part of the leg. The upper' part of the tubular leg i'svprovided with a longitudinal slot g extending over ture z' provided transversely through the upper telescoping member f. A washer j and-also a convex shield c embracing the exterior ofthe tubular part of the leg are interposed between the head h1 of the thumb such that on the thumb lscrew h being slack- 95.. I screw h and the leg, the arrangement being ened the .upper telescopic member f can be freely `slid within thel tubular leg member, within the limits of the longitudinal slot g,

whilst-on thethumb screw h being tightcned, the upper telescopic member is rigidly clamped in Aany .adjusted positlon. The

thumb screw h and screw-threaded aper` tures z' are located inwardly of the-leg framework, and the rotatable connections of the 75 member C having at each end an. aperture d through which is. passed a` counter-sunkrivet c adapted to rotatably connect to the construction to the upper frame described in my prior U. S. application Serial No. 392507, is adapted to be supported by the aforesaid transverse fiat strip members c, and is detachably secured thereto by screws Z passing through corresponding apertures in the strip members c and in the superposed transverse bars m of the seat frame, these screw apertures being located at conveniently spaced points in the length of the transverse members and being maintained in positive register by the rigid transverse bracing connection of the leg frame-work furnished by the transverse stripL members c. v

The seat bottom n may be formed of sheet metal as described in my said prior applitransverse cation, `or it may be alternatively made of ply Wood or like material secured to the rivets o as shown, or by equivalent means.

What I claim as m invention and desire to secure by Letters atent is: A

In metallic chairs, stools and the like of the -type described a plurality of tubular legs, transverse strip members, plugs telescopically arranged to coact with the upper ends of the tubular legs, rivet means countersunk in said strip, meansl for securing said plugs to said strip members?, a frame resting upon said strip members, a sheet of material rgidl secured to said frame, and means for etaehably securing said frame to said strip members.

In Witness whereof I have hereunto set my hand.
